We have three monitors down here at my desk featuring rooftop hive action. I made the pictures below by photographing the monitors so you could see what I see.
Here's this year's new hive, with the Italians

Bearding is a form of hive air-conditioning; the bees depart the immediate brood nest area in order to help keep it at the desired temperature (too many busy bee bodies = too many BTUs). When you see all the bees outside the hive an hour before sundown, you'll also notice the following morning (early a.m.), most if not all, have gone back inside the hive because the outside air temperature (and thus the hive temp) has dropped - again, just a way they regulate the brood nest temperature.Here's Hive 1, with an amazing lip beard(Kara's description and right on)
KirkoBeeo at Backward Beekeepers has this to says about bearding:
When we checked out the hive the bees were bearding on the outside of the hive. This is a sign of crowding and it being pretty hot.Since Noam checked the hives the last day of July and augmented their living space (top photo), we're not too concerned about crowding...but our Chicago weather has been nothing but hot and humid.
Introducing the third bee cam, just installed by Art, who wanted a side view. He noticed when the bees beard they pile on top of each other, forming a thick layer of bees atop bees.
Here are the Italians in a side view,
same moment as as the photo two up.

And by the way, there's another meaning to the term "bee beard"...
